PACKING-BOX FOR PAPER-FOLDING MACHINES.

SPECIFICATION forming part of Letters Patent No. 551,922, dated December24, 1895.

Application filed January 17, 1894. Serial No. 497,150. (No model.)

T0 all whom/ it may concern."

Be it known that I, TALBOT C. DEXTER, of Fulton, in the county ofOswego, in the State of New York have invented new and useful 7Improvements in Packing-Boxes for Paper- Folding Machines, of which thefollowing, taken in connection with the accompanying drawings, is afull, clear, and exact description.

This invention is designed to be used on paper-folding machines having aplurality of folders adapted to make either three or four folds, as maybe desired; and the invention consists essentially of the combination,with said folding-machine, of a packing-box supported under the foldersad justably to receive the paper from either the third or fourth folder,according to the operation of the machine; and the invention alsoconsists in certain novel features of the details of the aforesaiddevices, as hereinafter fully described, and specifically set forth inthe claims.

In the accompanying drawings, Figure l is a plan View of my adjustablepacking-box, showing the same in its two positions for receiving thepaper from either the third or fourth folder. Fig. 2 is an end view ofsaid packing-box in position for receiving the paper from the thirdfolder. 3 is an enlarged inverted plan view of said box with means fortransmitting reciprocating motion t0 the packer. Fig. 4 is a side viewof the Fig. 5 is an enlarged transverse seotion on line X X in Fig. land Fig. 6 is an enlarged transverse section on line Y Yin Fig. 2,showing the adjustable connection of the rock-arm to the rock-sh aftwhich operates the reciprocating packer.

Similar letters and numerals of reference indicate corresponding parts.

A represents the supporting-'frame of the folding-machine.

1 2 3 4: denote, respectively, the first, second, third and fourthfolders consisting of the usual blades disposed at right angles to eachother and in successive lower planes and introducing the sheet betweenrollers in the usual and Well-known manner. The means for operating saidrollers and folding-blades being also well understood and in no wiseaffectin g the operation of my present invention,

said means need not here be illustrated or described. The lines l 2 3 4merely indicate the positions of the successive folding devices. The twofolding devices designated by reference-iigure's 2 2 receive the paperslitted into two parts and fold said parts separately and simultaneouslyand impart to each its second fold.

O represents the packing-box, which is of the shape of a prolongedtrough for the receptionl of the folded sheets. In said trough is theusual packer P, which reciprocates lengthwise of the box and betweenbreasts P P', which latter are also movable to yield to the pressure ofthe packer sufficiently to allow the folded sheets to be packed againstthe breasts. The arrangement and operation of these packing devices arecommon to other packingboxes and well known to persons familiar with theart to which said devices pertain. The purpose of this invention is torender said packing-box adjustable in its position in relation to thefolders or folding rollers and blades so as to adapt said box to receivethe paper from either the third or fourth folder, and to that end Ipivot said packing-box so as to allow it to 4be turned in a horizontalplane and bring it into its aforesaid positions. For this purpose Iprefer to mount on one of theside rails near the bottom of the frame A astout metal plate d, which is provided with an elongated slot o. for thereception of the bolt by which said plate is fastened to the aforesaidrail. Said slot allows the plate to be adjusted in its position as maybe required to bring the box in proper positions under the folders. Upon`this plate is pivoted a bracket b the base of which is provided with asegmental slot b. concentric to the pivot. Through this latter slotpasses the clamping-screw b', which enters a screw-threaded socket inthe plate a and when tightened serves to retain the bracket in itsposition. To' the bracket b is fastened the packing-box C at or near thecenter of its length. Said box can thus be swung in a horizontal planeto lines at right angles to each other when the clamping-screw h isloosened.

To avoid contact of the box C with the legs of the frame Ain theoperation of turning said box into different positions, said box isformed IOO with a separable end section O, which can be removed and thusshorten the box sufficiently to allow it to be turned as aforesaid.

For operating the packer l? in either of the aforesaid positions of thebox C, I employ the rock-shaft O, to which is attached the arm D, thefree end of which is connected to the packer P by means of a rod c,attached at one end to said arm and at the opposite end to a short arm cfixed to a rod e, which extends along the exterior of the box C paralleltherewith and slides longitudinally in guides c c attached to the box.Another short arm f attached to the rod e has its free end connected toa stud affixed to the packer and projecting through a longitudinal slot7i in the side of the box. The rock-shaft O receives its motion from arotary eccentric d by the pitman Z connected to the eccentric-strap andto the arm B attached to the rock-shaft O.

To allow the packing-box C to be turned at right angles from under onefolder to a position under another folder, as hereinbefore described,without affecting the position of the rock-arm, I provide the rock-shaftwith two key-seats or pin-holes c' il at right angles to each other, asshown in Fig. 6 of the drawings, either of which is adapted to receivethrough it the key or pin t by which the rock-arm B is attached to theshaft O. By withdrawing said key or pin the arm B is loosened on theshaft and the latter can be turned with the other arm D to bring saidarm in proper position for operating the packer after the packing-boxhas been swung around to its requisite position. To further facilitatethe adjustment of the packing-box to its different positions I make therod c detachable from the short arm c', preferably by providing the endof the rod with an eye and forming the arm c with a trunnion 0, whichpasses through said eye and receives through its protruding end alinchpin n.

r r represent the fingers which are usually attached to the frame of themachine and extend downward therefrom and in such positions as toreceive between them the folded sheet descending from thefolding-rollers to the packing-box. Said iin gers engage the uppercorner portion of the sheet received in the packing-box and support saidsheet in upright position after the packer P has pushed it beyond thefingers toward either of the breasts P. In order to make one set of saidfingers perform the aforesaid function in either of the adjustedpositions of the packing-box C, I attach said fingers to the packing-boxand make them adjustable up and down to engage papers of differentsizes. Said adjustability is represented in the drawings of the form ofa vertical slot s in the plate s', to which both fingers are attached. Astandard u rises from the side of the box C and hasthe plate s attachedto it by a clamping-screw r passing through the slot s and into thestandard, as shown in Fi 4 of the drawings.

lVhat I claim as my invention is- 1. In combination with a paper-foldingmachine having a plurality of folders at right angles to each other, apacking-box pivotedl to swing from under one set of folders to aposition under anotherset of folders, a reciprocating packer in saidbox, a rock-shaft receiving motion from the actuating mechanism of thefolding machine, and an arm connected to said rock-shaft and actuatingthe packer, said arm being adjustable to accommodate it to differentpositions of the packing-box as set forth.

2. In combination with a paper-folding machine having a plurality offolders disposed at right angles to each other, a paper-packing boxsupported under the folders adj ustably to positions for receiving thepapers from different folders, a packer in said box, and fingersattached to the box adj ustably to support papers folded to differentsizes as set forth.

3. In a paper-folding machine having a plurality of folders disposed atright angles to each other, the combination with the supporting frame,of the plate CL-- secured to said frame laterally adjustable, thebracket lipivoted to said plate to turn in a horizontal plane, and thepacking-box -C- supported on said bracket as set forth.

4E. In a paper-folding machine having a plurality of folders disposed atright angles to each other, the combination, with the supporting-frame,of the plate asecured to said frame laterally adjustable, the bracket-hpivoted to said plate, the clamping-screw -hclamping said bracket adjustably in its position, the box -C- fixed to said bracket, the packerP in said box, the rock-arm -B receiving motion from the actuatingmechanism of the folding machine, the rockshaft O- having key-seats atright angles to each other for the reception of the attaching key of therock-arm and the arm D attached to the rock-shaft and actuating thepacker as set forth.

In testimony whereof I have hereunto signed my name this 16th day ofNovember, 1893.
